I am sending the newsletter every day but couldn't figure out which will be the suitable subject line for my email. I am on weight loose niche. Would you like to suggest me some subject lines which increase my open rates?

Here is the top type of email subject 1. The question subject line
Questions make great email subject lines because they get the reader to think about how the subject matter applies to their own life.

The best questions will resonate with the reader and their past experiences, while arousing a sense of curiosity to learn more about the subject and whether their experiences are similar to others.

For example:

Do you check your emails when you first wake up in the morning?

Are you a zombie without your morning coffee as well?

These subjects lines work because the reader can relate to these behaviors, but are also drawn to click-through to possibly learn more about whether others have similar experiences and what the possible implications of that behaviour is.

2. The ‘How to’ subject line
There’s an old saying in copy-writing circles that you can’t write a bad headline if it starts with the words ‘How to’.

The ‘How to’ subject line formula works so well because it forces you to describe the content of the email in very clear language. Take these 3 subject lines for example:

How to get better marketing results through beautiful design

How to win friends and influence people

How to get 1,000 new email subscribers in 1 day

By reading these subject lines, you know exactly what you are going to learn from opening the email.

The key to success with this subject line formula is focusing on the benefit. Nobody actually wants to learn another process or methodology, instead they want to get the end benefits of better marketing results or new email subscribers, so make sure when using a ‘How to’ subject line you focus on the benefits and not the process itself.

3. The scarcity subject line
Scarcity is a powerful driver of human behavior. When something is in short supply, our fear of missing out kicks in and we are compelled to act.

Adding a time or availability limitation encourages readers to open and act on your email before it’s too late. For example:

Only 2 days left to get 50% off shoes

Hurry! Only 3 consultation spots left.

Get free shipping if you order within the next hour

The key to using scarcity in your email subject lines is importance. If the reader doesn’t have any intention of purchasing from you, they are not going to care that they can get free shipping if they purchase in the next hour. You need to make sure the offer you are presenting is important to the reader before you bring scarcity into it to try to compel them to act quicker, otherwise the time or availability limitation you are imposing is irrelevant to them.

4. The announcement subject line
Using words like “Introducing” and “New” in your email subject line gives the reader a feeling that your email contains new, breaking information they haven’t heard yet.

In our recent study on power words in email subject lines, email subject lines that included terms like ‘Introducing’ and ‘New’ increased the chance of the email being opened by 9.45% and 3.26% respectively.

Examples of this formula in action include:

See our new design gallery

By using words like ‘Introducing’ and ‘New’ in the subject line, you are letting people know that your email contains new information they don’t know yet and are encouraging people to open the email and learn more.

5. The number subject line
Using numbers in your email subject lines is a great way to set people’s expectations and provide a structure for the content of your email.

Every time we A/B test our blog post headlines, we find that the version of the headline containing the number outperforms the one that doesn’t. For example, when we A/B tested ‘3 steps to measuring the success of your email marketing with Google Analytics against ‘How to measure the success of your email marketing with Google Analytics’, the subject line with a number got a 57% increase in opens.

So where possible, use numbers to make your subject line more specific. For example:

30 ways to build your email list

3 steps to sending beautiful email campaigns with Canvas

10 product announcement emails reviewed for conversion

The key to success with this formula is the number you use. If you are suggesting effort a reader needs to expend (like steps in a process for instance), then using a low number works better as it suggest the process is quicker and easier. However, if you are providing value to the reader (like a number of ways to increase email subscribers) then a higher number will work better as it increases the reader’s perception of the value your email will provide them.

Great suggestion indeed. Also I when send my emails with first name of the subject line the open rates is great. People love to see their name on the email subject line.

Make your headlines short and concise. You want subscribers to open your emails and possibly take some recommended action. This will weed out those who won't be interested in the contents of your email.

And if you can manage to evoke curiosity with just one word then use one word headlines that entice subscribers to open your emails.

There's no one method that works best. Experiment with as many as you can and you'll find one that works best for you.

The subject line can make or break your email, and if its not written correctly then that email you've sent won't even get opened.

People these days are becoming wiser and wiser when it comes to spam, and if there's even a hint of that in your subject line then they'll hit the delete button without even reading it.

It might sound simple, but if you look at the main reason for sending that email in the first place, then sum it up in the subject line. That's all you need to do. If your offering 50% off a product, then the subject line could be just that. 50% off (whatever it is your selling). Everyone likes a bargain after all...
